Step-by-step explanation:
someone help me answer this plzzzzz
Answer:
Step-by-step explanation:
r = (x co-efficient ÷ 2)²
r = (6/2)² = 3²
r = 9
s = - 2r
s = -2*9 = -18
-2x^2+8x-9+4x+7x^2+2
Answer:
Add like terms
Step-by-step explanation:
You want to combine the squared, the variables, and the constants.
Combine -2x^2 and 7x^2 to get 5x^2
Then combine 8x and 4x which is 12x
Then combine -9 and +2 which is -7.
You should get 5x^2 + 12x - 7.
Keep in mind you can only combine like terms that are in the same equals barrier
For example: You can combine 8x + 3 + 2x = 0
but not 8x +3 = 2x +0 because they are on different sides of the equal sign.

Which statement is true?
A. 3 2/5 < 2 4/5
B. 2/3 > 1 7/3
C. 4 1/4 > 2 3/4
D. 1/2 < 1/4
Answer: C. 4 1/4 > 2 3/4
Step-by-step explanation: Option C is correct because when comparing mixed numbers, we first compare the whole numbers. In this case, 4 is greater than 2. Then, if the whole numbers are the same, we compare the fractions. In this case, 1/4 is greater than 3/4. Therefore, 4 1/4 is greater than 2 3/4.

What is -5(-3r-3)=75
Answer:
r = 4
Step-by-step explanation:
-5(-3r - 3) = 75
Divide both sides by -5.
-3r - 3 = -15
Add 3 to both sides.
-3r = -12
Divide both sides by -3.
r = 4

If g(x) = 3x^2+2x-1. Find g(-1).
Step-by-step explanation:
g(x) = 3x² + 2x - 1
g(-1) = 3(-1)² + 2(-1) - 1
= 3(1) -2 -1
= 3 - 3
= 0
which value for x makes the sentence true? 1/40 + x = 1/8
Answer:
x = 1/10
Step-by-step explanation:
1/40 + x = 1/8
Subtract 1/40 from each side
1/40-1/40 + x = 1/8-1/40
x = 1/8 - 1/40
Get a common denominator
x = 1/8 *5/5 - 1/40
x = 5/40 - 1/40
x = 4/40
Simplify
x = 1/10

The probability that an event will happen is P(E)=
34/41.
Find the probability that the event will not happen.
Answer:
7/41
Step-by-step explanation:
There is a 34/41 probability that this event will happen so to find the probability of which the event will not happen, the subtract 34 from 41 to get your answer.
41-34=7
Therefore, 7/41 is the answer.
Ps. is the P(E) included in the main question? if it is, the the answer might differ from the one I am giving you.

If I spent $3.87 on grapes at Tom Thumb and I bought 3.05 pounds. How much was each pound?
(round to the nearest hundredths place because it is money)
Answer:
$1.26 or $1.27 depending on whether you round up or down. The number in the thousandths is an 8 though
Step-by-step explanation:
You would divide 3.05 by itself to get one pound
and then 3.87 by 3.05. You have to divide both numbers so you get the number for one pound.
3.87÷3.05=1.268852459
Round up or down depending on what your teacher would want you to do so that the decimal is in the hundreths like money.
2. What decimal equals seven hundred forty-six thousandths?
A. 0.0746
B. 0.7461
C. 7,400.6
1
D. 7,400.006
Answer:
A. 0.0746
Step-by-step explanation:
Because it is in the thousandths place

Find the area of a square with a side of length 2 Square root of 3+6 square root of 7 inches
Answer:
(264+24√21) in²Step-by-step explanation:
Area of a square = Length * Length
A = L²
Given the length of a square as [tex]2\sqrt{3}+6\sqrt{7}[/tex] inches' The area of the square will be calculated as shown;
[tex]A = (2\sqrt{3}+6\sqrt{7})^2\\\\A = (2\sqrt{3}+6\sqrt{7})(2\sqrt{3}+6\sqrt{7})\\\\A =(2\sqrt{3})(2\sqrt{3})+(2\sqrt{3})(6\sqrt{7})+(6\sqrt{7})(2\sqrt{3})+(6\sqrt{7})(6\sqrt{7})\\\\A = 4\sqrt{9}+12\sqrt{21}+12\sqrt{21}+36\sqrt{49}\\\\A = 4(3)+24\sqrt{21}+36(7)\\ \\A = 12+24\sqrt{21}+252\\\\A = 264+24\sqrt{21}[/tex]
Hence the area of the square is (264+24√21) in²
